关于Spring“cvc-complex-type.2.4.c: 通配符的匹配很全面, 但无法找到元素 'context:component-scan' 的声明”

错误： cvc-complex-type.2.4.c: 通配符的匹配很全面, 但无法找到元素 ‘context:component-scan’ 的声明。

在你的applicationContext.xml文件中添加如下代码即可解决

xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd

完整约束如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">
    

</beans>
